GARLAND – Water in a creek near Tinsley Park has "nearly returned to its natural state," Garland city officials said Friday.

The city believes cloudy water in the creek may have been caused by a leak or complications during construction on a wastewater line. 

In an effort to improve water quality, Garland's Water Utilities and Health Department staff "finished releasing fresh water upstream and draining the impacted water on Friday," a news release said.

The city, while having to deal with a significant number of dead fish, continues to test water samples to figure out the exact source of the problem.
